BEIJING (REUTERS) - China's military has recently completed a jet bomber drill over the South China Sea, the defence ministry said on Thursday (July 30).

H-6G and H-6J bombers participated in high intensity training round the clock, ministry spokesman Ren Guoqiang told a news conference.

China claims about 90 per cent of the South China Sea, with Brunei, Malaysia, the Philippines, Taiwan and Vietnam challenging its claims.
